GRS / GOTS / OEKO-TEX / RCS: Which Certifications Matter for Activewear Brands

When a customer drops into a deep squat, the fabric is stretched, pressed against the skin, and hit by light—often all at once. Whether the leggings still look "not see-through"in that moment is what people call Squat-Proof.

But for brands and factories, "not see-through" can't stay subjective. A truly squat-proof standard must be measurable, repeatable, and scalable across colors and production batches. That means breaking the concept into clear technical factors: light transmittance, yarn fineness/denier and cover factor, dyeing & finishing, and opacity under a defined stretch ratio.

This article turns squat-proof into a practical, supplier-ready language you can use for development and inspection—and shows how Bloomto helps established brands build consistent squat-proof leggings for long-term reorders.

The Future of Activewear Is Sustainable — And Bloomto Is Leading the Way

In a world where fashion meets function, sustainability has become the defining benchmark of excellence in activewear. Today's consumers seek not just performance but purpose — garments that empower movement while protecting the planet.

At Bloomto, sustainability isn't an afterthought; it's the very core of our DNA. Guided by our vision to become a global leader in active lifestyle innovation, Bloomto integrates eco-conscious materials, ethical manufacturing, and industry-recognized certifications to redefine what it means to wear "responsible performance wear."

We believe in creating an active lifestyle ecosystem built on health, comfort, and harmony with nature — where every product supports both people and the planet.

1. Understanding the Four Major Certifications for Activewear

At Bloomto, the GRS certification is one of our proudest achievements.

This standard ensures that recycled fibers — such as recycled polyester and nylon — used in our performance apparel are authentically sourced, safely processed, and ethically produced.

GRS also verifies:

• Recycled content through third-party validation

• Social responsibility and safe working conditions

• Chemical management to reduce harmful emissions

• Complete traceability across every production stage

By choosing GRS-certified materials, Bloomto proves that sustainable design can also deliver technical performance, durability, and style.

2. GRS (Global Recycled Standard): A Proof of Authentic Recycling

At Bloomto, the GRS certification is one of our proudest achievements.

This standard ensures that recycled fibers — such as recycled polyester and nylon — used in our performance apparel are authentically sourced, safely processed, and ethically produced.

GRS also verifies:

• Recycled content through third-party validation

• Social responsibility and safe working conditions

• Chemical management to reduce harmful emissions

• Complete traceability across every production stage

By choosing GRS-certified materials, Bloomto proves that sustainable design can also deliver technical performance, durability, and style.

3. GOTS (Global Organic Textile Standard): For Our Natural Fiber Lines

While activewear often relies on synthetics for performance, Bloomto is expanding into organic cotton yoga sets, bamboo-infused athleisure, and plant-based fabrics — all certified under GOTS.

GOTS ensures:

• 95–100% certified organic fibers

• Non-toxic dyeing and finishing processes

• Fair labor and environmental compliance

• Traceability from farm to finished garment

Our GOTS-certified pieces represent Bloomto’s commitment to comfort with conscience, blending natural softness with sustainable integrity.

4. OEKO-TEX® STANDARD 100: Skin-Friendly, Safe, and Trustworthy

Every Bloomto garment touches the skin, so safety is non-negotiable.

With OEKO-TEX® STANDARD 100 certification, our materials are rigorously tested to ensure they are free from harmful chemicals, allergens, and irritants.

This means every Bloomto product — from compression leggings to training tops — guarantees safety, breathability, and peace of mind.

We believe true performance begins with skin health and human well-being.

5. RCS (Recycled Claim Standard): The Foundation of Traceable Responsibility

For many products, Bloomto adopts the RCS certification as an entry-level verification of recycled content.

While less comprehensive than GRS, RCS provides transparent tracking of recycled inputs in our supply chain — ensuring our "eco"claims are always real and verifiable.

RCS lays the groundwork for our broader sustainability roadmap, as Bloomto continually upgrades to GRS across new product categories.

6. Bloomto's Commitment Beyond Certifications

Sustainability at Bloomto goes beyond paperwork and logos.

It's about conscious design, community impact, and environmental stewardship.

Our initiatives include:

• Green manufacturing processes that minimize water and energy waste

• Biodegradable packaging for all online shipments

• Solar-powered production facilities in selected factories

• Employee welfare programs that promote safe, fair, and empowering work environments

Bloomto stands as a model for "conscious manufacturing", where ethics and aesthetics coexist seamlessly.
